Again ... a false narrative .... the warm waters are cyclical as recorded
Are water temps in Florida Keys truly record setting? It’s complicated... ...........No sensor has ever recorded a temperature of 101° anywhere in the world’s oceans.
But there is some pause on this preliminary number.
Location, location, location
Measurement of water temperatures is notoriously difficult to find quality data.
Some sensors measure just the very top of the water, other sensors go several feet into the water.
At Manatee Bay, the sensor is located 5 feet below the water line, but the water is very shallow in this part of the Keys.
The sensor is also located in an area where little water circulation is likely. Manatee Bay is located north of the Keys, and is cutoff to some degree from the rest of the Florida Straits by land from mangroves and the Overseas Highway causeways...............
.....This area also is famous for significant organic matter, like algae and seagrasses. This can artificially inflate water temperatures as darker matter will absorb more heat.
It is the warmest ever recorded there?
Another major point of concern on this record by scientists is it may not be the warmest temp ever recorded at this sensor.
Scientists over the past couple of days have found that the sensor recorded a 102° temperature in August of 2017.
The sensor may have also gotten close to 100° in 2009 as well.
This brings doubt that the water temperature recorded earlier in the week will verify as a new world record.
. . .But it was still hot
Even if the 101.1° water temp isn’t verified, it was exceptionally hot in the Florida Keys, and it remains that way.
Water temperatures at other buoys, and remote sensing using satellites, have recorded water temps in the mid to even upper 90s around the Florida Keys.....................
